I was able to open up the run.bat file and it displayed the servers page. But now the servers page doesn't open up and it takes me automatically to single player mode.
The problem about the single player mode is I can't save or load any files I have in my computer.

I want to know if there is a way to play minecraft classic offline and be able to save and load your files in the computer.

I also want to know is if the world of minecraft client just connects to the server of minecraft.net. If it does, then isn't the same thing as using the website and playing minecraft classic on the original web page.

Please someone respond back and tell me if there is any possibility in fixing this issue or at least tell me if there is a way to get minecraft classic offline and be able to save/load files.
